Abstract

PROBLEM TO BE SOLVED: To shorten the construction term, facilitate the works, and improve the safety by excavating shallowly or eliminating the excavation for forming a basement. SOLUTION: Shallow trench 1 is formed by excavation in an original ground 5 and the basement 4 is constructed in the trench 1. The ground in the outer circumference of the basement 4 projected from the original ground is raised by banking 7 using excavated soil produced by excavation and the circumference of the basement 4 is covered by the banking 7.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method for constructing a basement.

[0002]

2. Description of the Related Art Conventionally, as a method of constructing a basement such as a house or a factory, as shown in FIG.
At the same time, the excavation 103 is formed by making a root cut at a depth substantially equal to the height of the basement 102 to be constructed.
A method of constructing the basement 102 as shown in FIG.

[0003]

As described above, if the root is cut at a height substantially equal to the height of the basement 102, labor for excavating the ground, arranging the reinforcement of the basement 102, and placing concrete is increased. There is a bulky problem.

[0004] In particular, the amount of soil 104 excavated by excavation increases, and the labor and cost required for the treatment increase. Also,
If a large amount of excavated soil is temporarily deposited on the premises, other vegetation on the premises must be damaged, or the landslides caused by rainwater must be concerned.

Accordingly, an object of the present invention is to provide a method for constructing a basement which solves the above-mentioned problem.

[0006]

According to a first aspect of the present invention, in order to solve the above-described problems, the ground is raised by embankment on an original ground, and the basement is covered with the embankment. This is a method for constructing a basement.

In a second aspect of the present invention, a shallow trench is formed in the original ground by root cutting, and a basement is constructed in the dug, and the root is formed on the outer periphery of the basement protruding above the original ground. This is a method for constructing a basement, characterized in that the ground excavated by cutting is embanked to elevate the ground, and the basement is covered with the embankment.

A third aspect of the present invention is characterized in that a basement is constructed on the original ground, the ground is raised by embankment on the outer periphery of the basement, and the periphery of the basement is covered with the embankment. How to build a basement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described based on the embodiment shown in FIGS.

FIG. 1 shows a first embodiment.

First, as shown in FIG. 1 (a), a relatively shallow dig 1
Is formed, and a dry area 2 and a pump 3 are provided therearound.

Next, as shown in FIG. 1 (b), a basement 4 is constructed in a part of the excavation with reinforced concrete or the like.
When the basement 4 is constructed, since the dug 1 is relatively shallow as described above, most of the basement 4 is exposed above the original ground 5.

Next, as shown in FIG. 1 (b), using the excavated soil 6 of the part of the excavation, an embankment 7 is formed on the outer periphery of the peripheral wall of the basement 4 to raise the ground. Cover.
Thereby, the basement 4 is buried with the soil.

In the case where a predetermined ground level cannot be raised only by the amount of the excavated soil 6 generated by the root cutting, the ground is raised by carrying soil from another place.

When raising the ground, the retaining wall 8 as shown in the figure may be provided near the boundary of the site. However, when the amount of raised ground is small, the retaining wall 8 may not be necessary.

In the drawing, reference numeral 9 denotes a drain.

As described above, the constructed basement 4 projects almost entirely upward from the original ground 5, but the surroundings of the basement 4 constructed as described above are filled and covered by embankment. Suitable as a legal basement.

According to the above construction method, the excavation work can be performed easily and early because the excavation 1 by root cutting is relatively shallow. Further, since the construction of the basement 4 can be performed near the original ground 5 (the ground), the construction work can be performed easily and early. Furthermore,
Since the amount of excavated soil is small, temporary storage of the excavated soil is also easy, and there is less fear of damaging other plants in the site or collapse due to rainwater. Furthermore, since the depth of the digging 1 is also shallow, the danger of the worker falling down during the construction can be reduced and the safety can be improved. In addition, the influence of construction noise and vibration disturbance for excavation on the adjacent land is small, and work near the boundary of the adjacent land can be performed easily.

FIG. 2 shows a second embodiment.

In the present invention, as shown in FIG. 2A, the basement 4 is first constructed on the original ground 5 without cutting off the original ground 5 as shown in FIG. 2B. Next, on the outer periphery of the constructed basement 4, soil 7 brought from another place is embanked 7, and the outer periphery of the basement 4 is almost covered with the embankment 7. Thereby, the basement 4 is buried with the soil. If necessary, the retaining wall 8 is constructed in the same manner as described above.

According to the present embodiment, since root cutting is not required, the work can be facilitated, the construction period can be shortened, and the worker can be prevented from falling into the dug compared to the conventional method. . Furthermore, there is no need to temporarily store excavated soil. Also,
It can be built near the neighboring land, and there is little noise and vibration.

[0022]

According to the present invention, the ground is raised by embankment on the original ground, and the surroundings of the basement are covered with the embankment. Alternatively, it may be a shallow root cutting. Therefore, compared with the conventional method of deep root cutting, the construction period is shortened, the work is facilitated, the problem of excavated soil treatment is solved, and the danger of work due to deep excavation is avoided. Work safety.
